IMPROVBD SEPARATOR FOR MEAL, cc.

The Schedule referred to in these Letters Patent and making part of thesame.

To allk whom tt may concern Beit known that I, WILLIAM HAWKINs, ofBrooklyn, in the county of Kings, and State of New York,

have invented and made a new and useful Improvement in separators forMeal, Snc.; and I do hereby declare the following to be a full, clear,and exact description of the said invention, reference being had to lthe annexed drawing, making part of this speciiica- Figure 1 is alongitudinal section of the said separator, and

Figure 2 is a cross-section of the same.

Similar letters denote the same parts.

Sieves and sifters of different kinds have been made,

but usually any foreign matter that may be retained in the sieve has tobe emptied by inverting said sieve.

My invention relates to a pecnliarity in the siftingapparatus, wherebythe operation is made continuous, the meal, or similar material, heiligdelivered at one place, and the material that does not pass through the.

sieve at a separate opening. n

My invention consists in a shaft, set in adjustable bearings,andcairrying elastic agitators and inclined conveyers, combined with acase having a semicircu- Ilar screen at the bottom, a hopper forreceiving the meal or .material passing through the sieve, and anopening at the end of the semicircnlar screen, through which rtheconveyers deliver the uusifted material.

In the drawinga is a shaft, to be revolved by competent power.

The pulleys b and c, and belt, allow the machine to be driven byhand-power applied to the crank-handle ll.

The shaft a is set in bearings ef, withinthe frame g, and h i areadjusting-screws for these journalboxes.

Between the frames g are the side pieces k and top l, forming the case,and rm, is the semicircular sieve, placed between the sides k, and overthe hopper n, that receives and delivers the'meal or other materialsift-ed through m.

Upon the shaft a there is a series of elastic agitators, o o, arrangedin a spiral position between the inclined conveyers p p, which also forma spiral or screw form upon the shaft a, so that the material will be lcaused to progress from the end at which it runs in from the hopper. q,to the end where the unsifted maf terial is delivered from the separatorby the spout fr.

It will be understood that this apparatus is especially intended as alight portable separator, for family use, and the operation beingcontinuous, greatly facilitates its use.

The inclined conveyers also act as agitator-s, and the'elastic agitatorso o act to force the nieal through the sieve, and by their contact withthe sieve, to keep the same from becoming clogged.

What I claim, and desire to secure by Letters Patent is- 'he shaft a,with the agitators o, and inclined conveyers p, arranged as set forth,in combination with the adjustable bearings e f, case k l, screen m,hopper n, and delivery-spout fr, as and for the purposes set forth.

In witness whereof, I have hereunto set my signa.- ture, this 10th dayof May, 1869.
